Solution Overview

Problem

Training pilots of aircraft poses unique challenges due to the need for physical flight and remote operation, which are hindered by signal, communication, and control latency caused by large distances between control centers and remote vehicles, affecting decision-making during operations.

Innovation Solution

A virtual reality flight emulator system that uses galvanic vestibular stimulation (GVS) and visual cues to simulate the motion and orientation of aircraft, allowing users to control and operate remote or virtual vehicles through a pilot control interface, with the ability to virtually teleport into slave vehicles to reduce latency and enhance training and operation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If remote vehicle operation is implemented to avoid physical flight training requirements, then training safety and accessibility are improved, but signal, communication, and control latency increases due to large distances between control centers and remote vehicles

Engineering Contradiction:
Improvetraining accessibilityVSAvoidcontrol latency
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces a virtual reality emulator as an intermediary system that locally simulates remote vehicle behavior and environmental conditions. This emulator runs on the operator's local device, eliminating the need for real-time communication with distant vehicles for basic training scenarios, thus reducing latency while maintaining training accessibility

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a local copy of the remote vehicle's behavior patterns, environmental conditions, and operational characteristics through the VR emulator. This copy allows operators to practice control procedures and decision-making locally without requiring actual connection to remote vehicles, thereby eliminating communication latency for training purposes

Inventive Principle:
Principle #26Copying

2Reliability

If physical flight training is required to ensure safe and effective operation, then operator skill and situational awareness are improved, but training cost and risk increase due to requirements for actual aircraft flight

Engineering Contradiction:
Improveoperator skillVSAvoidtraining system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical system of actual aircraft flight with a virtual reality simulation system that uses galvanic vestibular stimulation. This substitution maintains the sensory feedback and operational training value while eliminating the need for physical aircraft, reducing training complexity and risk

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the physical parameters of training by using galvanic vestibular stimulation to simulate motion sensations without actual movement. This allows the operator to experience flight-like sensory feedback while remaining stationary, simplifying the training system while maintaining skill development effectiveness

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If galvanic vestibular stimulation is added to the VR system to enhance motion simulation, then realism and operator immersion are improved, but device complexity and cost increase

Engineering Contradiction:
Improvesimulation realismVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The galvanic vestibular stimulation device serves multiple functions: it provides motion sensation feedback, enhances immersion, and can simulate different flight conditions and maneuvers. This multi-functionality justifies the added complexity by delivering multiple training benefits from a single system addition

Inventive Principle:
Principle #6Universality (Multi-functionality)

Motion of, orientation of, and/or forces acting on the slave virtual or remote aircraft (204) are imparted to a user (110) through a plurality of galvanic vestibular stimulation (GVS) devices (117) when the user (110) of the flight emulator (100) is virtually teleported into the slave virtual or remote aircraft (204). The flight emulator (100) can be connected through a communication network (208) to a plurality of other flight emulators (100). The flight emulator (100) can also be installed in an aircraft and connected through the communication network (208) to a plurality of other remote aircraft (204a1-n).
